ICD-10 Code I74.2 – Embolism and thrombosis of arteries of the upper extremities (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I74.2 – Embolism and thrombosis of arteries of the upper extremities
What it is
I74.2 identifies an arterial blockage in the upper limb caused by an embolus or a thrombus. It applies when the obstruction involves arteries of the arm, forearm, or hand.
Clinical signs
Typical findings include sudden limb pain, pallor, coolness, numbness, or reduced pulses. Clinical features vary; refer to documentation for the affected artery and whether the event is embolic or thrombotic.
When to use this code
Use this code when the record documents embolism or thrombosis affecting an upper-extremity artery. It is appropriate for acute arterial occlusion, including cases described as limb ischemia when the site is the arm or hand. Verify laterality and any associated cause if documented.
Do not use for
Do not use I74.2 for venous thrombosis, superficial thrombophlebitis, or nonvascular arm pain. If the note does not clearly identify an arterial embolus or thrombosis, check documentation.
Coding tip
Match the code to the documented vessel and keep embolism versus thrombosis consistent with the provider’s wording.
